I believed I was ordering a NEW spam call blocker. Imagine my surprise when I opened the package and found a box with a seal saying REFURBISHED. There was absolutely no indication when I ordered this item that it was anything other than new.

We’re so glad to hear our CPR Call Blocker is already reducing your spam calls and has stopped 15 unwanted calls in just two weeks. That's so great to hear. We really appreciate your support.
Although, my landline phone model was too antiquated for the unit I purchased CPR was gracious enough to allow me a refund, plus the ability to keep the product and donate it to my church for a fundraiser.

Thank you so much for your thoughtful review.
It’s wonderful that you chose to donate the unit to your church fundraiser. What a generous gesture!
The directions for setting up the device were clear. This product is very easy to use.

We’re so glad to hear that the setup was clear and that you’re finding the CPR Call Blocker easy to use. That’s exactly what we aim for.
We truly appreciate you taking the time to share your experience.
Does not block calls in my area code (928) automatically. I have to get up go to the device and manually block. A wireless remote would be very helpful for those calls.
Reply from CPR Call Blocker USA2026-02-20
Hello Jerry ... Good news; you can auto-block an entire area code (like 928) so you won’t need to manually block each call.
To block an area code:
Lift the handset and enter:
Press *
Press *
Press 7
Press #
(wait for the beep)
Enter Area Code
Press #
(wait for the beep)
Hang up
Once set, all calls from that area code will be blocked automatically.
If you need any further help, don't hesitate to call us or use our website support.
Thanks,
CPR Team
Hello Victor, We completely understand how frustrating it can be not to receive an order. Unfortunately, we’re currently unable to ship the CPR V100K Call Blocker to your address in Mexico. When your order was reviewed, you should have received a notification explaining the situation at the time the refund was initiated.
The good news is that your refund has already been processed, and you should see it reflected in your bank account. If you don’t see it yet, please check with your bank, as processing times can vary slightly.
Kind regards,

I bought this for my parents. It's helped with some of the robot calls, I wished it took care of the several "Medicare call" . My Mom got a call from my nieces phone number, it was Medicare. They need to get a real job. Overall, it's stopped 60% of the scam calls

Thank you for sharing and for helping protect your parents 😊
We’re really pleased the CPR Call Blocker is already stopping around 60% of those nuisance calls! Those sneaky spoofed “Medicare” calls can be frustrating, but we’re always working to stay one step ahead of them.

Thanks for taking the time to leave a review.
The CPR Call Blocker usually starts working once it’s connected and programmed in a way that suits your particular phone setup. Landline configurations can vary, and in some cases an alternative connection method or a quick programming tweak is all that’s needed to get things working as expected.
We’d love the chance to help. Please get in touch with our support team and we can go through your setup together, suggest alternative connections if needed, and make sure the blocker is tailored to your requirements. We’re confident we can get it working properly for you.
Received CPR call blocker and it was very easy to install. It has worked great and I have been receiving fewer calls. Before buying I checked great reviews of this product. Company is topnotch as is product. Cannot go wrong buying this blocker.

I bought this for my mom’s house line and it has worked perfectly. She said she gets pleasure out of pushing the big RED “BLOCK” button. Haha
Reply from CPR Call Blocker USA2026-01-15
Thanks so much for the brilliant review - and for making your mum's day a bit brighter!
We're thrilled the CPR Call Blocker is working flawlessly on her house line, and it's even better knowing that big RED BLOCK button brings her such joy. Nothing beats the satisfaction of giving nuisance callers the boot!
If there's anything else we can do to keep the good vibes (and blocks) going, just let us know.
Hello John. It is possible to add numbers from your wireless (cordless) handset. The good news is our CPR Call Blocker works perfectly with DECT cordless phones.
From any handset (corded or cordless), just:
Get a dial tone
Dial * * 7 # (beep)
Enter the number to block
Press # (beep to confirm)
This should work seamlessly from your cordless phone.
If it’s still not beeping or working as expected, please contact our support team - we’ll happily guide you through it.
Thanks again for choosing CPR Call Blocker.
My 1* review is based on shipping/delivery experience only. The website states "All products are shipped within 24 hours using either standard USPS postal service (2-7 days) or if chosen USPS expedited service (1-3 days). Complaints: 1) Communication is non-existent and/or false. 2) I paid $15 for 1 day service but my order was delivered via Amazon not USPS 8 days after I placed the order. 3) The label for my order was created 4 days after I placed my order! 4) Shipping actually occurred 6 days after my order was placed, not 24 hours as stated on their website.
2/26/26update - I have the documentation of shipping date, it was not on Monday. And yes, I did receive the $15 credit for expedited shipping....after I disputed it with my credit card.

Thank you for your feedback - we understand the frustration caused by the delivery delay.
Your order was placed on Saturday 20th December (weekend). We apologise for any lack of clarity; we process and ship within 24 working hours, so yours was sent out first thing Monday 22nd via our nearest fulfilment partner, Amazon Warehouse.
Unfortunately, the peak Christmas rush led to longer courier delays than expected. We’ve spoken with Amazon Fulfilment about this case and noted your points for improvement.
We’ve already refunded the full $15 shipping fee for your original order.
We appreciate your honesty and hope to serve you better next time. Please reach out if there’s anything else we can do.
Best regards,
CPR Team
Fantastic! We're so pleased he loves it – another happy household saved from the dreaded nuisance calls. Thank you for the great review and for giving him the gift of a peaceful phone!
I've had a couple of issues. Caller name is not displayed and second the screen bounces between the call list and the blocked list. Sometimes I'm not sure which list I'm viewing. When I clear the list, it's the wrong list.
Reply from CPR Call Blocker USA2026-01-20
Thank you for sharing your feedback. To answer your questions:
For caller names, the device shows the number from your landline's Caller ID service - names depend on your provider sending them. It might be worth confirming with them that full Caller ID (with name) is enabled on your line.
On the screen bouncing and list confusion, we understand how annoying that is. Use the dedicated "Calls List" and "Block List" buttons to switch, and double-check you're in the right view before deleting.
Thanks again for choosing CPR Call Blocker - we're glad it's blocking those unwanted calls and are here to make things smoother for you!
Best regards,
The CPR Call Blocker Team
CPR call blocker is an excellent product. I have had one for many years and it still works great. I ordered one for my brother for his Birthday, Your Company sent the unit through Amazon. After two weeks of no delivery. Amazon lost the package. They claim that I was to contact CPR for reimbursement. I called two different numbers and received a message to go on line for answers on your worthless web site for answers. Then the call is terminated. I'm out $69.99 for the lost product. I'd like reimbursement. I have already purchased a unit from Amazon and received said unit for more money. I would like to get my $69.99 back and you need to answer your service call phones.

We understand your frustration and disappointment - especially with this being a birthday gift for your father. We hate that it didn't arrive as expected.

We have passed on your comments to our courier providers to help improve the service.
1. Answer my requests for help.
2. Block spoofing calls.
This tool might block calls from specific numbers after I notify it that a call is (another) spammer. But I can't tell, because the bad guys use other people's numbers to fool us into answering. If you try to reach them, they'll issue a case number, but nothing more.
Reply from CPR Call Blocker USA2026-01-20
Thank you for your honest Trustpilot review. We completely understand the frustration of spoofed calls where numbers keep changing.
Our V100K call blocker comes pre-loaded with over 100,000 known scam numbers for automatic blocking, and you can instantly block any that get through with the big red "Block Now" button. Many customers find that blocking similar area codes or prefixes helps cut down persistent calls even more.
Our support team is ready to help with setup, compatibility, or advanced options to reduce those remaining calls further.
